BOOT OR SHOE HOLDING JACK.

SPECIFICATION forming part of Letters Patent No. 362,347, dated May 3, 1887.

Application filed March 1 1887. Serial No. 229,296. (No model.)

To aZZ whom it may concern.-

Be it known that I, GHARLEs J. ADDY, of Malden, county of Middlesex, and State of Massachusetts,have invented an-Improvement in Boot or Shoe Holding J acks, of which the following description, in connection with the accompanying drawings, is a specificatiomlike letters on the drawings representing likeparts.

This invention has for its object to improve, simplify, and strengthen jacks, especially those employed in machines for burnishing the heels of boots or shoes.

In accordance with this invention, the spindle of the clamp entering the shoe is operated by a lever and cam, both the lever and cam having a projection which cooperates to arrest the movement of the cam on the arrival of the lever in each of its extreme positions.

Figure 1 in side elevation represents asufficient portion of a jack of the kind used in what is known the Tapley Burnishing-Machine to enable my invention to be understood, and Fig. 2 is a plan 'view of Fig. 1.

The foot-step A, the rod B, and the arm a of the U-shaped or forked head 0 are common to the Tapley bnrnishing-machine. The arm I) of the head 0 is provided with a suitable box or sleeve, (1, slotted at its upper side, as at (1. (See Fig. 2.) This box or sleeve receives and forms a guide for the spindle e,which enters the shoe, the said spindle having the pivoted foot or end piece,e,to bear against the inner side of the shoe over the heel thereof, the toplift end of which rests in the notch or seat a".

arrest the rotation of the scroll-cam g, employed to move the said lever in the direction to clamp a boot or shoe. The cam g is secured to a short shaft, 9, to which is secured a handwheel, 9. I

In Fig. 1 the toe 3 of the'scroll-cam g is shown as engaging the lowermost shoulder of the heel f of the lever f,and the spindle is retracted.

When it is desired to actuate the spindle to clamp a boot or shoe to be bnrnished,the handwheel 9 will be turned in the direction of the arrow 4, Fig. 1, which moves the cam g, causing it to act upon the heel f and move the lever f forward positively and with great power, and finally the projection 3 ofthe cam meets the shoulder 4. of the lever f, when the further movement of the cam in that direction is arrested. 7

I claim- 1. In ajack for holding boots or shoes, the spindle, its box or gnide,and the spindle-actuating lever,combined with a cam to move the said lever, substantially as described.

-2. Thejack-head and spindle and lever to move it, provided with a heel having a proj ections, combined with a cam having a projection,3,to be arrested by the shoulders of the saidheel, substantially as described.

3. In a jack-for holding boots or shoes, the spindle, its box or guide, and the spindle-actuating lever,combined with a cam to move the said lever and with the hand-wheel to move the shaft carrying the said cam, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
